Code Eclipse is quite old and is no longer supported. You're still welcome
to use it, and it still works (for the most part) with PHP4 compatible code.
It does not understand objects, namespaces, and newer built in functions.
Eventually I may get around to updating it, however for now it's offered "as is".

Code Eclipse is a PHP obfuscator. It turns normal, easy to read PHP code
into gibberish, with little to no loss of speed and no loss of compatibility.
I developed Code Eclipse because I needed a way to hide the source code
for one of my scripts as much as possible while still retaining 100% compatibility
with PHP servers. Other options like Zend Encoder work great for people
who have control over their servers, but I wanted to reach the entire
PHP audience, which includes a LOT of people who don't admin their own
servers.

In the process of looking for a decent PHP obfuscator all I could find
were commercial scripts (retailing for upwards of $250) and a couple free
ones that just didn't do as much garbling as I wanted. Even many of the
commercial ones produce output that's difficult, but still possible to
read without any translation. Specifically they still used PHP's function
names and didn't obscure strings, making it relatively easy to guess what
the functions were doing.

Code Eclipse is NOT an encryptor. Some products out there (like Zend
Encoder) actually encrypt your code. This is good and bad. It's good because
your code is further protected against theft. It's bad because encrypted
code requires special modules to run, and, while those modules are usually
free they are not installed on the majority of servers, which means administrator
intervention will be required to get it running. If you're distributing
a $2000 script to a select list of clients, then you should probably be
using an encryptor to safeguard your application because chances are you
have influence over what software their server will be running. For the
rest of us there's services and products like Code Eclipse.

(Note that there are also some products out there that claim to encrypt
code with no modules needed. Read the fine print carefully and get a techie's
opinion before purchasing said product. I have yet to see anything that's
anywhere near secure, or, for that matter, even a deterrent. One I found
simply zipped the code into a password protected zip file, and then unzipped
it on EVERY PAGE LOAD. Of course the password was being stored in the
"decryptor" script, so all you need to do is open it up in your
favorite zip software and type in the password to access the code. This
and they estimate a 1 to 3 SECOND additional load time, EVERY TIME the
page is hit, in order to decompress / decrypt the page!)

Code Eclipse is currently in beta and is (for the moment) a free service.
It should be pretty safe to use on your code (eg: it should produce executable
code with no modification) however if you find bugs please let me know
and I'll see what I can do to fix them. Currently it garbles variable
names (except for super globals such as $_SERVER), user function names,
php function names, array keys, double quoted strings, and heredoc strings.
Due to the way PHP interprets single quoted strings there's not much we
can do to garble them, so if you want to reveal as little as possible
use double quoted or heredoc strings. It does a few things to make the
code even more unreadable, including creating variables with the same
names as functions and vice versa, multiple (randomly selected) methods
of encoding string characters, etc. And of course it removes all comments
and any non-critical white space (line breaks and spacing inside a string
is left alone). It's not optimized fully yet so it will probably increase
the size of your code slightly. I have a few ideas to fix that (hopefully
getting the code size smaller than your original) as well as making things
even more difficult to reverse engineer. When I get a moment I'll implement
them.
